Creating SFTP Algorithms

To select encryption algorithms (ciphers)

In EFT Administrator, connect to EFT Server and click the Server tab. (SFTP should be enabled.)
In the left pane, click the Site you want to configure.
In the right pane, click the SFTP Settings tab.

In the Use encryption algorithms list, clear or select the check boxes to specify which algorithms you want to allow for encrypting SFTP sessions.

Twofish - Twofish is an improved version of Blowfish. It provides the strongest security available in GlobalSCAPE EFT Server and should protect your data in most transfers. GlobalSCAPE EFT Server recognizes Twofish encryption using 128 and 256 bit keys.
Blowfish - The Blowfish algorithm is a public-domain block cipher method using a 128-bit key. Blowfish was intended to be a replacement for 3DES. It provides good security.
Triple DES (3DES) - This algorithm uses a 24-bit "triple key" to encrypt data 3 times. The 24-bit key is split into 3 8-bit segments and each is used for encryption. Triple DES is fast, but not as strong as the other algorithms.
ARCFOUR - Arcfour is intended to be compatible with the RC4 cipher trademarked by RSA Data Security, makers of the famous OpenPGP program. It uses a 128-bit key and provides good security.
cbc - Cipher Block Chaining is an encryption technique used with block ciphers where the previous encrypted block is used as a basis for encrypting the next block, so that every block has to be in the correct order to be decrypted properly.
CAST128 - CAST block cipher using 128 bit keys.
aes128 - Advanced Encryption Standard (AES) block cipher using 128 bit keys.

Click Apply. EFT Server tries each selected algorithm with the client until one is agreed upon.
